Multiphoton Ionization of Uracil at 355 nm

We present the experimental results from ionization and dissociation by multiphoton absorption (MPI) of uracil and a mixture of uracil with Ar using a Reflectron time of flight spectrometer along with radiation from 355 nm at pulsed Nd:YAG laser . We focus on the light ions production. The MPI mass spectra show that the presence and intensity of the resulting ions depend on the density power of...

48 GHz Power Amplifier for mm-wave LO Distribution Circuitry in 90 nm CMOS

—A 48 GHz fully integrated two stages power amplifier (PA) for mm-wave application is presented in this paper. The PA is implemented in 90 nm LP CMOS technology with Cascode topology to enhance gain and stability. The single ended PA achieves around 15 dB small signal gain, 4.5 dBm saturated output power and a peak power added efficiency of 9% in measurement. Patterned ground shield coplanar tr...

Transceiver in 90 nm CMOS for 10 mm On - Chip Interconnects

The bandwidth of global on-chip interconnects in modern CMOS processes is limited by their high resistance and capacitance [1]. Repeaters that are used to speed up these interconnects consume a considerable amount of power [2] and area. Recently published techniques [1-4] increase the achievable data rate at the cost of high static power consumption, leading to relatively high energy per bit fo...

THE 90-mm PERIOD UNDULATOR FOR SRRC

The U9/SRRC undulator has recently been completed by STI Optronics, Inc. (STI) for use at the Synchrotron Radiation Research Center (SRRC) in Hsinchu, Taiwan, R.O.C. This 4.5-m long, 90-mm period wedged-pole hybrid undulator builds on several aspects of previous STI designs [1] while including a number of significant enhancements. The magnetics are based on the wedged-pole geometry [2] with add...
